IMPROVEMENT IN BARREL-TRUSSING MACHINES.

Specification forming part of Letters Patent No. 211,914, dated February4, 1879; application filed September 9, 1878.

.To all whom it may concern:

Be it known that I, HORACE W. KING, of

Alden, in the county of Erie and State of New York, have inventedcertain new and useful plete, and Fig. 2 a side elevation of the same.

Fig. 3 represents a plan or top view of the expanding and contractingbed; Fig. 4, a central transverse section through the base of themachine, cutting the lower bed through line X X, Fig.3. Fig. 5 is acentral section cut diagonally through the base and through the lowerbed in line Z Z, Fig. 3; and Fig. 6 represents a portion of an annularhead, around which the upper ends of the staves are set, and a sideelevation of the device for holding the truss-hoop, showing, also, asection through a part of the truss-hoop and the upper portion of astave. y

This machine is an improvement on the invention for which Letters PatentNo. 200,733 were granted to me February 26, 1878. Its object is toprovide the means for rapidly setting up the staves of a barr'el andapplying the truss-hoops thereto; and it consists, first, in an annularhead provided with devices for carrying the truss-hoop, and with aconical or tapering portion, between which and the hoop the upper endsofthe staves are placed when set up, the arrangement being such that bya downward movement of said head the truss-hoop is partly forced overthe upper ends of the staves, while the conical portion forces thestaves outward, so as to form a true circle within the truss-hoop. Theconical portion also serves to center the barrel truly.

The second part of my invention consists of a separable bed havinggrooves to receive the lower truss-hoops, and sections provided withpieces projecting outwardly and held to stationary supports by pivotedarms, the

lower ends of the sections resting in a coni-' cal rim or depression,and the upper ends against the outside of an annulardownwardlyprojecting conical rim, in combination with a ring or annularplate, and a suitable means for connecting it to the movable trusshoopdriver, as will be more clearly hereinafter shown, the combination beingsuch that as the truss-hoop is forced partly over the ends of the stavesthey are forced outward, so that their edges will be even and theirouter surfaces form a true circle against the inner sides of thetruss-hoop, and so that the sections of the separable bed will not bedriven apart, by the power required to force the barrel into the lowertruss-hoops, but, on the contrary, will be held closer together by suchaction.

The third part of my invention relates to the means employed to regulatethe movements of the upper or movable truss-hoop driver and it consistsin the combination of a movable truss-hoop driver, a rack-an d-pinionmovement for actuating it, and a system of grooved friction-gearing witha brake and suitable levers for operating them, whereby the downwardmovement of the truss-hoop driver may be instantly arrested at any time.

In said drawings, A represents the frame of the machine; B, the upper ormovable trusshoop driver, consisting of a hollow cone having offsets fordriving the truss-hoops, as shown in my said patent. It is kept inposition in the frame A by means of the projections B which pass intoopenings A, and is kept in a vertical position by the rack-bars O, whichare rigidly fastened to B and pass through the transom 0, therebyallowing a free vertical movement of the driver B. Motion is imparted toit by the grooved friction-gear D cl, pinions cl, and driving-pulley D.

E represents the annular head, supported by the shaft E, frame 0 andtransom G. e c are adjustable collars to limit its motion.

F represents the conical portion projecting downward therefrom, againstthe tapering sides'of which the upper ends of the staves f are set, (seeFig. 6,) the lower ends resting on the top of the base G, as shown bydotted lines F, Fig. 4. f is the truss-hoop, which is only partly forcedover the upper ends of the staves by the head E, as in Fig. 6, the headB afterward forcing it in place. The trusshoop f is held in place by theholders f which are pivoted to E at 9, so as to be readily turnedoutward, and the spring-hook g, (which is pivoted to f at 9 so as to beeasily turned down to catch and hold the truss-hoop, as shown in Fig. 6.There are three or more of the holders f and the hoop is released byspringing them outward, after which they are turned up out of the way,as in Fig. 1.

The separable bed (see Figs. 3, 4, and 5) is made in sections B thelower parts of which are set in the circular tapering depression G andthe upper parts, which are beveled, as shown, are set against theoutside of the tapering rim G The letters H represent pieces projectingradially from the sections B and rigidly fastened to them, and by whichthey are each jointed to an arm, h, and to a stationary support, 7L2, asin Fig. 5. The inner lower parts of H rest on a hoop, I, at ha. The hoopI encircles G and is provided with pieces t', (see Fig. 4,) projectingout from each side, to which are connected the arms J, (see Figs. 1, 2,4,) which are provided with collars J, (see Fig. 1,) fastened to each.

It will be seen that as the truss-hoop driver B moves up and the parts Breach the collars J, a further movement will lift the arms J, hoop I,and the sections B with their connections, so as to raise and separateor expand the separable bed, as shown in Fig. 5.

The upward movements of the driver B are controlled bythe levers K K andconnectingarm K the driving-pulley and small frictiongear being held byadjustable boxes I, so that by means of said levers the friction betweenthe grooved gears D and (1 may be increased or diminished, andconsequently the upward movement of B maybe arrested instantly whenrequired. The downward movement of B is controlled by the levers L M,connecting-rod N, and grooved brake O, the object being to stop it inits descent at any time, or hold it at any point while thedriving-pulley is runnin g, and the lever K is lifted so that thefriction-gearin gs are sufficiently apart to prevent wear, all of whichwill be readily understood by reference to Fig. 2. The brake and itsparts are so constructed that the weight of the levers L M is sufiicientto hold the driver B at any point.

As the driver B moves up and down, the separable bed opens and closesautomaticallyopening to receive the truss-hoops or to let them out withthe barrel, and closing or contracting so as to receive and inclose thetrusshoops, and hold them while the barrel is being trussed or forcedinto them.

It will be noticed that the staves are set up (in this machine) on alevel bed, and the mechanism is such that, as set up, they are level andtruly centered, and are not forced out of place whilebein g contracted,or while the trusshoops are being driven; consequently aleveling deviceis not required after the trusshoops are on.

I claim as my invention-- 1. The combination, in the driver, of theannular head E, lower tapering portion, F, and devices for supportingthe truss-hoop f constructed and arranged substantially as and for thepurpose described.

2. The truss-hoop driver B B, arms J, hoop or plate I, and rims G G ,incombination with the separable bed, connected to stationary supports,substantially as specified.

3. The combination of the vertically-reciprocating frame carrying thedriver, the shaft, with pinions d, gearing into racks on said frame, andcarrying the frictiou-pulleyD, with the friction-pulley it, and brake 0,all operating substantially as and for the purpose set forth.

HORACE KING.
